Description
Technical field
This utility model relates to a kind of heating rod, is combined quartz ampoule heating rod particularly to a kind of rustless steel.
Background technology
Heating rod is widely used in the electrical heating in the fields such as industry, petrochemical industry, civilian household electrical appliances.Existing heating
Rod mainly has two kinds, and one is to be made up of alloy resistance wire, magnesia powder mineral insulation and steel tube dirt-proof boot；
Another kind is to be wrapped on insulation board by alloy resistance wire, and outside arranges insulating barrier again.These two heating rods
Exothermic material is METAL HEATING PROCESS silk, and not only electric conversion efficiency is low, can only achieve 72%, and oxidizable,
Life-span is short.
For improving electric conversion efficiency, people have invented carbon fiber heating rod.Existing carbon fiber heating rod is
By internal carbon fiber exothermic part be enclosed within the quartz glass tube outside heater and constitute.This carbon fiber heating
Rod is the most not only easily broken, and service life is short；And be not easy to when using install and fixing.
Summary of the invention
It is high that technical problem to be solved in the utility model is to provide one not only electric conversion efficiency, and not
Broken, service life is long, it is simple to install and the rustless steel fixed is combined quartz ampoule heating rod.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of rustless steel is combined quartz ampoule heating rod, including being located at the carbon fiber exothermic part at center, at carbon fiber
Outside heater, sealing shroud is provided with quartz ampoule, and carbon fiber exothermic part two ends are crimped with molybdenum rod, molybdenum rod outer end respectively
Being sealed by quartz ampoule respectively and draw, be filled with nitrogen in quartz ampoule, it is characterized in that: outside quartz ampoule
Being arranged with oversheath, described oversheath is to be crimped by stainless steel band and draw along longitudinal seam welding to form, and protects outside
Sealing respectively in the port at set two ends and be installed with insulation pipe collar, described molybdenum rod outer end is sealed by insulation pipe collar respectively
Pass, between oversheath and quartz ampoule, be filled with heat-conducting glue.
As further preferably, described carbon fiber exothermic part is helical form and is woven by 6 strands or 12 strands of carbon fibers
Form.
As further preferably, described insulation pipe collar is ceramic material and is bonded in oversheath two by insulating cement
In the port of end.
As further preferably, described quartz ampoule inner chamber is the vacuum state of-0.1Mpa, and by the nitrogen being filled with
Gas reaches quartz ampoule internal and external pressure balance.
The beneficial effects of the utility model are:
1, owing to using carbon fiber as heater, without visible ray in heating process, electric conversion efficiency is up to
98%, use under the condition of high temperature and do not aoxidize, the load of the electric current of its unit are does not changes.Additionally heat passes
Lead speed to be directly proportional to heater surface area, and the single diameter of carbon fiber only has 0.02mm, existing carbon fiber heating
Body to be made up of several ten thousand carbon fibers, and its surface area is big is that heating alloy body cannot be comparable.Therefore, carbon
Fiber heating cable can realize energy-conservation reaching more than 30% compared with traditional heating alloy body.
2, owing to being arranged with oversheath outside quartz ampoule, oversheath is to be crimped by stainless steel band and weld along longitudinal joint
Connect drawing to form, between oversheath and quartz ampoule, be filled with heat-conducting glue, therefore under the protection of oversheath not
Broken, service life is long, and during use, oversheath is easily installed and fixes.

Detailed description of the invention
As depicted in figs. 1 and 2, a kind of rustless steel that this utility model relates to is combined quartz ampoule heating rod, bag
Including the carbon fiber exothermic part 1 at the center of being located at, described carbon fiber exothermic part 1 is helical form and by 6 strands or 12 strands
Carbon fiber braiding forms.Outside carbon fiber exothermic part 1, sealing shroud is provided with quartz ampoule 2, carbon fiber exothermic part 1
Two ends are crimped with molybdenum rod 6 respectively, and molybdenum rod 6 outer end is sealed by quartz ampoule 2 two ends respectively and draws, quartz ampoule 2 liang
End is sealed by high temperature sintering, and described quartz ampoule 2 inner chamber is the vacuum state of-0.1Mpa, and by being filled with
Nitrogen is to reach quartz ampoule 2 internal and external pressure balance.
Being arranged with oversheath 4 outside quartz ampoule 2, described oversheath 4 is to be crimped by stainless steel band and along longitudinal joint
Welding drawing forms, and seals respectively and be installed with insulation pipe collar 5, described molybdenum rod in the port at oversheath 4 two ends
6 outer ends are sealed by insulation pipe collar 5 respectively and pass, and are filled with heat-conducting glue 3 between oversheath 4 and quartz ampoule 2.
Described insulation pipe collar 5 is ceramic material and is bonded in the port at oversheath 4 two ends by insulating cement.
During use, carry out wiring energising by the molybdenum rod 6 at carbon fiber exothermic part 1 two ends as binding post,
